Application June 6, 1932. Serial No. 615,704 2 Claims. (01. -252) Thisinvention relates to springs such as are used in cushions, seats andmattresses.

The invention has especial reference to means to sustain the top edgesof articles of the char- 5 acter mentioned, and including those using adouble deck spring.

The principal object of the invention is to provide a spring embodyingmeans of such character that the top edges of the article in which thespring is used will be yieldingly sustained without robbing the articleof its cushioning or pillowing effect, and also keeping said top edgesfrom sagging or breaking down, to thus preserve the normal condition andshape of the article.

A further object is the provision of means of the indicated characterwhich will be simple, inexpensive and of efiicient and substantialdesign.

The nature of the invention and its distinguishing features andadvantages will appear when the following specification is read inconnection with the accompanying drawing, in which Figure 1 is afragmentary side view of a spring selected to illustrate an embodimentof the invention;

Figure 2 is a section on the line 2-2 of Figure 1, the springs beingshown in elevation.

Figure 3 is a perspective view of one of the cushion springs.

Figure 4 is a perspective view of the upper end of a cushion springshowing a modification.

In the drawing, the invention has been shown, by way of example, inconjunction with a double deck spring. It is to be understood that thisspring may be used in cushions, seats and mattresses. The spring shownincludes a base or lower deck and a top or upper deck on the base orlower deck. The base deck includes a suitable supporting base 10 andcoil cushion springs 11 which are arranged in rows and which have theirlower coil portions secured to the base 10 as at 12. It is to beunderstood that the springs 11 will be interconnected by suitable means,and

additional means will be provided which is connected with the base 10and the springs 11 to limit the upward flexure of the springs 11. Thesaid means for the stated purpose is well known n and has been omittedfor the sake of clearness. The top or upper deck includes webbing 13 andcoil cushioning and pillowing springs 14. The

webbing 13 has a bound marginal edge and is laid on the uppermost coilsof the springs 11 and n, is secured in any suitable manner thereto. Thesprings 14 are arranged in rows and the lowermost and also the uppermostcoils thereof are connected together. The lowermost coils of the springs14 are secured to the webbing 13. The

uppermost coils of the springs 14 form an upper supporting structure forthe outer covering or upholstery (not shown). The springs 11 and 14 areof relatively different compressive strength,

the springs 11 being of greater strength than the springs 14. Thesprings 11 take up most of the weight imposed, whereas, the springs 14serve as a cushion, and pillow the upholstery. Use is made of a frame 15which may be constructed of metal, willow or any other suitablematerial.

The frame 15 aids in supporting and giving shape to the covering orupholstery, and, in fact, forms a top edge support. The marginal rows ofsprings 14 have their uppermost coils connected with the frame as at 16to keep the frame from spreading.

In accordance with the principal feature of the invention there isprovided means of such character that the top edges of the cushion,seat, mattress or the like in which the spring is used will beyieldingly sustained without robbing the article of its cushioning orpillowing effect, and so also keeping said top edges from sagging orbreaking down to thus preserve the normal condition and shape of thearticle. The said means is arranged between the springs 11 and the frame15. In the present instance, the means is arranged 5 between themarginal rows of the springs 11. The said means as shown in Figures 1, 2and 3, and appearing most clearly in Figure 3, is formed integral withthe uppermost coil portions of each spring in the marginal rows. Thesaid means, designated 1'7, is of arcuate formation in con tinuation ofthe upper end of the spring, and is disposed substantially vertical. Themeans 17 is secured to the frame 15 in any suitable manner such as bythe use of cord 18 or the like. The frame 15 may be provided with agroove or the like to receive the means 17, as shown in Figure 2. Fromthe foregoing it will be apparent that any weight imposed on the frame15 will be sustained mainly by the springs 11 thereby relieving thesprings 14 which serve merely as relatitvely soft cushioning means, andalso perform the function of pillowing the upholstery. Due to thegreater strength of the springs 11 which are connected with the frame15, the frame 15 will 5 be properly yieldingly sustained, and in thisman ner the top edge of the article, such as a cushion, seat or mattressin which the spring is arranged, will be kept from sagging or breakingdown during the life of the spring.

The same result hereinabove described may be accomplished by providing arigid connecting member 19 in lieu of the means 17. Said member 19consists of a horizontal portion 20 connected with the uppermost coil ofa spring and a vertical portion 21 which is integral with the portion20. The portion 21 hastmeans 22 on its upper end for connection'with thetop" edge frame 15.

Weclaim:

1. A double deck spring including a base deck of relatively stiffsprings, a top deck of relatively soft nonyieldingly interconnectedpillowing springs on the base deck, an upholstery supporting top edgeframe connected with the marginal springs of said deck of pillowingsprings, and the marginal springs of said base deck springs havingupturned arched members formed from the material of the upper end coilsthereof and extending upwardly therefrom in contact with said frame andsecured thereto so as to yieldingly sustain the frame and also toprevent lateral movement and sagging of said top deck of pillowingsprings.

2. A double deck spring including a base deck of relatively stiffsprings, a top deck of relatively soft nonyieldingly interconnectedpillowing springs on the base deck, an upholstery supporting top edgeframe connected with the marginal rows of said pillowing springs, andrigid means connected with and supportetd on the upper end coils of themarginal rows of said base desk springs, and extending substantiallyvertically upwardly therefrom, in contact with the said frame andsecured thereto, so as to yieldingly sustain the frame and also toprevent lateral movement and sagging of the said top deck of pillowingsprings.
